Atlantis has held a perennial place in the collective imagination of humanity from ancient Greece onward. Many of the great minds of the occult and esoteric world wrote at length on their theories of Atlantis - about its high culture, its possible location, its ultimate demise and their predictions of a return to Atlantean enlightenment or the downfall of modern society. Beginning with a review of the rationalist writings on Atlantis - those that use geographic and geologic data to validate their theories - renowned scholar, Joscelyn Godwin, then analyses and compares writings on Atlantis from many of the great occultists and esotericists of the 19th and 20th centuries, including Fabre d'Olivet, G. I. Gurdjieff, Guido von List, Julius Evola, Edgar Cayce, Dion Fortune and René Guénon, whose writings often stem from deeper, metaphysical sources, such as sacred texts, prophecy or paranormal communication. Seeking to unravel and explain the histories and interpretations of Atlantis and its kindred myths of Lemuria and Mu, the author shows how these different views go hand-in-hand with the concept of cyclical history, such as the Vedic system of the four Yugas, the Mayan calendar with its 2012 end-date, the theosophical system of root races and the precession of the equinoxes. Venturing broader and deeper than any other book on Atlantis, this study, also, covers reincarnation, human evolution or devolution, the origins of race, and catastrophe theory.
